Re: When an interest in valves becomes out of control without realising!
Most gas stabilisers will run for thousands of hours before the internal resistance (i.e.the "impedance" of the discharge) caused by changes to the composition of the gas used therein rises to an un-acceptable level. They then exhibit poor regulation, and sometimes a reluctance or failure to "strike", and this makes replacement neccessary
The life expectation is governed somewhat by the gas purity, but mainly by the operating current. I have known of several that have had operating lives of many years. Tony
